MP3 Player with TouchPad And TextLCD Display

Page last updated 14 Oct 2011, by Pramod Nataraja. 1 reply MP3 Player, mpr121, TouchPanel, VS1053

Project by Pramod Nataraja and Vishnu Venkataraman

Purpose

Playing mp3 files present on micro SD card using a audio Decoder VS1053. This project also includes a touch interface for input and TextLCD for display.

Description

Initially SD card was stored with music files named 1.mp3 to 6.mp3 under the folder /sd/music/. MicroSD and VS1053 communicates over SPI to the mbed. TouchPanel communicates over I2C. Depending on the touch panel input pressed particular song is read from the SD card and is sent over to the audio decoder which plays the music through a speaker connected to it. Other features are Play/Pause, Mute/Unmute, Previous Song/Next Song. Volume also can be controlled using the touch Panel.

Possible Improvements

This project assumes the songs are fixed and always 6 songs are available to Play so this might be improved to detect the songs in the specific folder and play it.
The names of songs can be decoded from the filename and displayed rather than assuming the song names in a character array.
